[0003] Conventionally, crib monitoring systems provide audio and/or video
feeds to allow users (e.g., parents) to observe what is happening in a
baby's crib. However, there are several problems associated with the
conventional crib monitoring systems. These crib monitoring systems fail
to provide an alarm or other warning when a baby comes within close
proximity to a side of the crib. If the baby gets caught in the side bars
of the crib but does not cry, the user may not realize that the baby is
in danger, thereby resulting in injuries to the baby.

[0004] Therefore, it is desirable to have a crib monitoring system that
includes a warning mechanism to allow a user to receive a warning to
thereby prevent the occurrence of injuries to babies.

SUMMARY

[0005] The present invention obviates the above-mentioned problem, by
providing a crib monitoring system for a crib that allows a user to
receive a warning when a baby therein is within close proximity to the
side bars of the crib and in danger of being injured.

[0006] According to one embodiment of the present invention, a crib
monitoring system for a crib having a plurality of crib posts disposed a
predetermined distance apart, and a side gate including a plurality of
bar portions disposed between and connectable to the crib posts. The crib
monitoring system includes at least one camera device connected to a crib
post of the plurality of crib posts and configured to capture an image of
an interior of the crib, a plurality of sensor devices, each sensor
device connected with a respective crib post, and configured to form a
signal beam along an interior surface of the side gate between the crib
posts, and a monitoring device configured to receive a warning signal
when a baby within the crib is within a predetermined distance of the bar
portions such that the signal beam is interrupted.

[0007] Additional features and advantages are realized through the
techniques of the present invention. Other embodiments and aspects of the
invention are described in detail herein and are considered a part of the
claimed invention. For a better understanding of the invention with the
advantages and the features, refer to the description and to the
